[PATCH] tools: hv: suppress the invalid warning for packed member alignment

[Saurabh Sengar]

Packed struct vmbus_bufring is 4096 byte aligned and the reporting
warning is for the first member of that struct which shouldn't add
any offset to create alignment issue.

Suppress the warning by adding -Wno-address-of-packed-member flag to
gcc.
